<p>Find Java Native Interface (JNI) libraries.</p>
<p>JNI enables Java code running in a Java Virtual Machine (JVM) to call
and be called by native applications and libraries written in other
languages such as C, C++.</p>
<p>This module finds if Java is installed and determines where the
include files and libraries are.  It also determines what the name of
the library is.  The caller may set variable <code class="docutils literal notranslate"><span class="pre">JAVA_HOME</span></code> to specify a
Java installation prefix explicitly.</p>
<div class="section" id="result-variables">
<h2>Result Variables<a class="headerlink" href="#result-variables" title="Permalink to this headline">¶</a></h2>
<p>This module sets the following result variables:</p>
<dl class="simple">
<dt><code class="docutils literal notranslate"><span class="pre">JNI_INCLUDE_DIRS</span></code></dt><dd><p>the include dirs to use</p>
</dd>
<dt><code class="docutils literal notranslate"><span class="pre">JNI_LIBRARIES</span></code></dt><dd><p>the libraries to use (JAWT and JVM)</p>
